Appt ication filed September 5', 1929. Serial No. 350,557.

The present invention irelates to lasts and more especially to animpifo've'd hinged last.

One of the objects of the invention is to provide a simple, eflicient ndeconomical con- 5 necting means for a hinged last which will maintainthetoe and heeliparts of the last in tight and proper positioh at alltimes and will not become worn or loose due to constant usage.

A further object. of the invention consists in connecting the toe andheel parts of the last bya rigid member, soithat the transverse anchorpins which pivotally secure the rigid member in position, will bemaintained .at their proper distance at all times, thus prepins when theparts of the last are moved relative to one another.

A further object comprehends the provision of guard members positionedbetween the rigid member and the adjacent side walls of the last, toprevent the parts from becom- I ing loose or worn due to the frictionalengagement of the rigid member with the side walls of the last, saidguard members being constructed and arranged to permit the rigid memberto be moved relative t'iereto when the forepart and heel part of thelast are moved to either their expanded or'contracted positions.

Other objects and advantages of the-invention will become apparent fromthe following description when taken in conjunction with ,theaccompanying claims and drawings.

In the drawings which disclose several pre ferred embodiments of theinvention,

Figure 1 is a side elevation of the last in expanded position with partsin section.

' Figure 2 is a view similar to Figure 1, show ing the last in collapsedposition.

Figure 3 is a sectional viewtakens'ub'stantially along the line 3-3of-Figure 1.7 Figure 4 is an exploded view of the connecting means.

' Figure 5 is a side elevation of a modified form of the invention,with-parts in section,"

and showing the last in its expanded position.

Figure 5, with the last in its collapsed positron.

- Figure 7 is an-exploded view of the connecting means shown in Figures5 and 6.

Referring to the drawings in which like numerals indicate like parts, inthe several views, 10 generally denotes a hinged last for .boots orshoes, which is composed of the toe part 11 andthe heel part 12, the toepart-11 preferably being provided with a transverse- 1y disposed concaverecess 13 ar'ran ed to receivea complementary formed knuc le 14, on theheel part 12, s'o-as to provide a socket oint for permitting-the partsto be moved relative to each other. The inner face 15 of t e heel partis cut away to allow the last to be moved from its extended position to1ts collapsed position while the downward movement of the last islimited by the abuttlng faces 16 formed on the lower portions of the toeand heel parts.

The forepart 11 and heel part 12 are formed disposed cut-away'portions17 and 18, which,

whenthe parts are in their expanded position, are in alignment with"each other.

Mounted within the 'cut-awa portions 17 and 18 is a rigid metallic memor preferably in the form of an elongated flat plate 19, which may be ofany suitable shape or configuration and has adjacent its ends theopenings 20 and 21' (Fig. 4). The rigid member '19 is pivotally'mountedwithin the cut-away portions 17 and 18 by the anchor pins or bolts 22and 23- which extend transversely openings 20 and 21." Associated withthe throughthe toe part 11,"heel part 12 and the I plate 19, are themetallic guard members 24:

and 25, which are arranged between the plate 5 19and the adjacent wallsof the cut-away portions 17 and 18, so as to 'preventthe plate19 I frombeing brought into frictional en-gage- 'ment'with the side walls of saidcutaway portions when the toe and heel parts of the last are moved fromone position to another.

Each of the guard members or plates 24 and 25 is. "provided adjacent itsends with openings 26 of slightly larger diameter than the openings20'and 21 and in alignment therewith, so as to receive the anchor pins22 and 23, when the parts are set up.

By reason of the free movement imparted to the plate or center piece 19,relative to the guards 24 and 25, means are provided for preventing theplate-l9 from being brought into wearing contact with the adjacent wallsof the cut-out portions 17 and 18, thus preserving the snug and tightfit initially put into the last when the parts are assembled.

Due to the ri idity of the plate 19, the anchor pins 22 and 23 areprevented from yieiding or stretching when the toe and heel parts aresnapped into either their expanded contracted positions and consequentlythe anchor pins will b maintained at all times .in their proper andcorrect position while the etficiency of .the last will be unaliected byconstant usage.

Inthe modified form of'theinvention illustrated in Figures 5, 6 and 7,the toe part 27 is pivotally connected to the heel-part 28 of the lastby a substantially rigid plate 29 which is provided adjacent its endswith the openings 30 for receiving the anchor pins 31 which extendtransversely through these parts and the cut-out portions 32.

In order. to prevent the plate 29 from being brought into rubbingengagement with the adjacent walls of the cutout portions 32, a

guard plate -is provided, whichvplate is preferably-composed of thesplit sections 33 and 34 that are substantially U-shaped incrosssection, so as to constitute the parallel sides 35 and SS-betweenwhich the plate 29 is positioned. The guard members 33 and 34 are eachformed adjacent their outer'ends with the openings 37 which are ofsubstantially the same diameter as the openings 30 in the plate 29 andare supported by the anchor pins 31 when the parts are set up.

In order that the plate 29 may be moved relative to the guard memberswithout these members riding therewith when the last is carried toeither-its. expanded or contracted positions, the inner opposed faces 38or" t guard members are preferably inclined spaced from each other. Theguard n bers and 34, in addition to preventing plate 29 from beingbrought into rubbing gagement, with the adjacent walls of the also tendto takeup and receive the strr. from the pins 31 and thus insurethe-parts from becoming worn or-loose.

It is to be understood that the sevez forms of theinvention herewithshown described aremerelyillustrative of preterm embodiments and thatsuch changes may be made. therein as fall within the purviewof oneskilled inthe art without departing from the spirit of the invention andthe scope of the appended claims.
